Answer: D.
Explanation:
Because...
Plants convert carbon into oxygen and chemical energy so without carbon they wouldn't have food/energy so they wouldn't be able to live.
* Therefor, the correct answer is D.
* Hopefully this helps:) Mark me the brainliest:)!!
The electron transport chain refers to the transfer of
electrons from electron donors and electron acceptors. After the transfer of
electrons, these electrons then couple with protons (H+ ions) across a
membrane. In eukaryotic cells, electron transport chains occur within the
mitochondrial membrane where it serves as the site of oxidative phosphorylation
that uses ATP as its energy source.

The molecular oxygen is the final acceptor of electrons in an
electron transport chain. This type of transport is used by the cell in
extracting energy through redox reactions that occur during photosynthesis,
sugar oxidation, and cellular respiration. </span>
Answer:
5.12μg of DNA
Explanation:
PCR is a method use to amplify DNA. It often require primers ( short sequence) nucleotides, heat stable polymerase enzymes, and thermocycler.
DNA strands are double by every cycle of PCR and it denoted by the formula 2^n where n is the number of cycle.
starting with 5ng,
the amount after 10 cycles = 2¹⁰ × 5 ng = 5.12μg of DNA
